Comprehensive Character Frequency & Unicode Analytics
Character frequency analysis measures how often individual characters, symbols, and whitespace appear in a body of text. It is widely used in computational linguistics, cryptography, font engineering, and copyediting.
This tool generates a detailed character-by-character frequency table with category breakdowns (letters, numbers, whitespace, punctuation, symbols, emojis), Unicode code points (U+XXXX), hex values, and percentage distributions.
Core Tool Capabilities
- Unicode Code Point & Hex Table: Detailed breakdown of every character's Unicode code point (U+XXXX) and hexadecimal value.
- Categorical Classification: Automatic classification into uppercase, lowercase, numbers, whitespace, punctuation, symbols, and emojis.
- Searchable & Sortable Grid: Filter characters by query and sort by frequency (high to low, low to high) or character order.
- Exportable Analysis Reports: Copy full analytical text summary or export a TXT report for documentation.

Practical Real-World Use Cases
Cryptanalysis & Cipher Solving
Analyze letter frequencies to assist in solving substitution ciphers and code breaking.
Font & Typeface Design
Identify most frequent characters in target languages to prioritize glyph design.
Data Cleaning & Sanitation
Detect unexpected hidden whitespace characters, non-standard control codes, or invalid characters.
Linguistic Research
Measure character distribution and letter usage across corpus samples.
Frequently Asked Questions
- How does the tool handle emojis and surrogate pairs?
- The analyzer uses Unicode code point segmentation, treating emojis and multi-byte surrogate pairs as distinct single characters.
- Can I filter whitespace characters?
- Yes. Toggling 'Whitespace Labels' makes space, tab, line feed, and carriage return explicit as [Space], [Tab], and [Line Feed].
- What sorting modes are available?
- You can sort by Frequency (High to Low), Frequency (Low to High), or Character Alphabetical Order.
- Is my text data private?
- Yes. All text processing is browser-local.
